AK7835S5

Overview

The AK7835S5 is a high-performance, low-power stereo audio CODEC manufactured by Asahi Kasei Microdevices. It integrates two differential microphone inputs and two differential line outputs with integrated programmable gain amplifiers. The device supports 24-bit resolution at sampling rates up to 192 kHz for both analog-to-digital and digital-to-analog conversion paths. It features a dedicated headphone amplifier capable of driving low-impedance loads directly. The component utilizes an I2S-compatible serial interface for digital audio data transmission and control.

Feature Summary

• Integrated dual differential microphone preamplifiers with programmable gain control
• Built-in headphone amplifier supporting direct drive of low-impedance headphones
• Supports high-resolution audio processing with 24-bit depth and up to 192 kHz sampling rate
• Low power consumption design suitable for portable battery-operated devices

Applications

• Smartphones and mobile communication devices
• Portable media players and digital audio recorders
• Tablets and handheld gaming consoles
• Voice recognition modules and smart speakers

Procurement Notes

Verify the specific suffix 'S5' against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target system's voltage levels and clocking requirements before integration. Cross-reference the part number with authorized distributors to confirm authenticity and availability status.

Selection Notes

Select this component when a compact solution is required for high-fidelity audio capture and playback in space-constrained mobile applications. It is appropriate for designs needing integrated microphone biasing and headphone driving capabilities without external discrete components. Consider the power budget and interface compatibility with the host processor during the selection phase.

Part Context

This model belongs to the AK78xx series of audio CODECs from Asahi Kasei Microdevices, designed for consumer electronics. The series emphasizes low power efficiency and high signal-to-noise ratio performance. The AK7835 variant specifically targets stereo input/output applications with integrated analog front-end stages for microphones and headphones.

Replacement Considerations

Consult official substitution lists from Asahi Kasei Microdevices for verified equivalents. Check pinout compatibility and register map differences if replacing with other models in the AK78xx family. Verify that any substitute maintains the required 24-bit resolution and sampling rate support.
